srLAs HoEFMAN LA RUE. or @WNW v ,i Letters Patent No. 105,816, dated July 26, 1870'.

The Schedule referred to in these Letters Patent and making part of the same To all who-ni, it nun] concernV v B it known that I, Sums HOFFMAN LA RUE, of

Allentowm in the county of Lehighland in the State of Pennsylvania, have invented certain new and useful'Improvexnentsin Stoves; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had vto the accompanying drawing and to the letters of reference marked therei on making". a part `of this specitication.

The nature of` my invention consists* First, in placing the supply air-flue above the base of the fireibox; i i

Second, in the construction of contractors'forming the throat of the magazine; and

Third, in introducing at the top 'of the stove a waterreservoir, in which the top is set.

In order to enable Vothersslrilled in the art to which my inventionappertains `to make and use the same, v I will now proceed to` describe its construction and stove.

A represents f the `o-utside'shell or cylinder Aof the stove, having an inside drum or V`cylinder, D, forming the magazine.

Between the two cylinders, A and D, is` the supply `air-flue B, which is so arrangedas-to enter above the 4base of the ire-box C, instead of in the base, as is usually the ease.

v'lhe holes in the cylinders A D for this supply-due may be opposite each other or one above the other, as shown, only so that there w1l1\be a downward draught 'lhe object of this is to produce combustion up to the point of\the {ire-box or maga- `zine aty whichthe due B enters, so ythat the gas generated in the' new coal may be forced through the column of fire below, thereby more, perfectly burning the'fuel. I f

In the magazine D are placed two contractors, E E, of curved form, as shown, attached opposite each other and' extending downward and inward, the one onv the side where the supply air-fluek B enters beingA directly against said entrance and below the other contractor, forming a throat in the magazine and cansing the air supplied through the due B to turn downward, as represented by arrows in the drawing. These will prevent the coal from ig'niting above the draughtflue. l a

In the top of the stove between thecyiinders is formed a water-reservoir, G, in which the top H is set, 'to prevent the admission of air to the magazine, and also, by evaporation, -to meisten the air of the room.

-Having thus fully described my invention, y

What I claim as new, and desire to secure b y Letters Patent, is- 1 l. Thel'contractors E E, 'constructed as described,`

forming thethrcat of the magazine D, substantially as and for the purposes herein sety forth.

2. The combination of the cylinder A, reservoir G, air-due B, magazine D, and contractorsEE, all substantiall y as set forth.

In testimony that I claim the foregoing, I have berelmto set my hand thisd day of- May, 1870.
